Many marine service companies are acquiring boat-towed metal detectors and magnetometers to assist in salvage operations and geophysical surveys. These devices can locate a variety of targets including sunken vessels, ship anchors and propellers, pipelines, cables and metal debris which must be removed from an area before dredging. The two primary pieces of equipment used in these operations are a magnetometer and the pulse induction (PI) metal detector. Magnetometers are super sensitive instruments that can detect iron and steel objects at hundreds of feet away.

Leak Turns Ship's Cargo to Cement

Cement dust aboard a ship bound for Adelaide has been contaminated by sea water, turning the cargo into cement, the Australian Broadcasting Corporation has reported. The incident reportedly occurred aboard the CSL Yarra, a 46,000 ton bulk carrier. "A fire hydrant has leaked sea water into a machinery space which has residual cargo from the last discharge," Australian Maritime Union South Australian secretary Rick Newlyn is reported to have said. "It was cement and that's of some concern, but not enough to change the voyage."
